Title:
PRESSING MEMBER AND FIXING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/009527
Kind Code:
A9
Abstract:
Provided is a pressing member such that the warm-up time required for increasing the temperature of the pressing member to a temperature sufficient for fixing unfixed toner is reduced and such that wrinkles along the circumferential direction of the pressing member are suppressed. The pressing member includes a base, an elastic layer formed on the outer side of the base, and a surface layer containing a fluororesin formed on the elastic layer, the surface layer being stretched in the longitudinal direction of the pressing member and fixed on the elastic layer. The porosity of the elastic layer is between 20 vol% and 60 vol%, inclusive, and E(MD)/E(ND) is larger than 1.0, where E(ND) represents the elastic modulus of the elastic layer in the thickness direction, and E(MD) represents the elastic modulus of the elastic layer in the longitudinal direction of the pressing member.
